They are just like the continuous waves. 它们看起来就像连续起伏的波浪一样。
Propagation Behavior of Electromagnetic Pulses and Continuous Waves(CW) Excited by the Same Energy 等激励能量的电磁脉冲与连续正弦波的传播规律的分析
The continuous pulse waves are obtained in time domain by calculating the space displacements of the feature points on movement image with single CCD camera. 在单个CCD摄像头固定的情况下,建立投影几何模型,计算所获取的动态图像上特征点的空间位移,得到时域上连续的脉搏信号。
That technology is based on analog signals, which mimic the scenes and sounds observed by a camera and render these as continuous electronic waves. 该技术是以模拟信号为基础的,由摄像机模拟观测到的景物与声响并将其变为连续的电波。
Ships involved in the search are faced with the problem of looking for debris that may be partly submerged amid continuous rolling waves up to 30 meters ( 98 feet ) high, according to some ocean experts. 一些海洋专家说,参与搜索的船只必须在不断翻滚的海浪中寻找飞机碎片,海浪高度最高可达30米。
